Oxidative stress plays an important role in the development of osteoporosis. The present cross-sectional study focuses on mapping single nucleotide polymorphisms (SNPs) in the mitochondrial manganese superoxide dismutase (SOD2) gene in Asian Indians. The bone mineral density (BMD) of study subjects was assessed by dual x-ray absorptiometry. Individuals were classified as normal (n = 82) or osteoporotic (n = 98). Biochemical parameters such as vitamin D, total oxidant status (TOS) and SOD2 enzyme activity were estimated from plasma samples. Semi-quantitative PCR was carried out using GAPDH as an endogenous control. Genomic DNA was isolated from whole blood and SNPs were evaluated by PCR sequencing. Thirteen SNPs are reported in the examined region of the SOD2 gene, out of which in our samples SNPs rs5746094 and rs4880 were found to be polymorphic. Allele G of rs5746094 (intronic) and allele C of rs4880 (exonic) are significantly higher in the osteoporotic individuals. Presence of allele C of rs4880 and increased level of TOS among osteoporotic individuals were found to be associated with disease risk.

2-dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione (DMDD) is a cyclohexanedione compound extracted from the roots of Averrhoa carambola L. Several studies have documented its beneficial effects on diabetes, Alzheimer's disease, and cancer. However, its potential neuroprotective effects on Parkinson's disease (PD) have not yet been explored.

Ulcerative colitis is a long-term inflammatory colon illness that significantly affects patients quality of life. Traditional medicines and therapies often come with challenges such as side effects, instability, unpredictability, and high costs. This has captured interest in natural products that have huge health benefits.

Exaggerated neuronal excitation by glutamate is a well-known cause of excitotoxicity, a key factor in numerous neurodegenerative disorders. This study examined the neurotoxic effect of monosodium glutamate (MSG) in the brain cortex of rats and focused on assessing the potential neuroprotective effects of omega-3 polyunsaturated fatty acids (ω-3 PUFAs). Four groups of adult male rats (n = 10) were assigned as follows; normal control, ω-3 PUFAs (400 mg/kg) alone, MSG (4 mg/g) alone, and MSG plus ω-3 PUFAs (4 mg/g MSG plus 400 mg/kg ω-3 PUFAs).

Objectives: Ischemia/reperfusion (IR)-induced ventricular arrhythmia, which mainly occurs after the opening of coronary artery occlusion, poses a clinical problem. This study aims to investigate the effectiveness of pretreatment with coenzyme Q (CoQ) in combination with mitochondrial transplantation on IR-induced ventricular arrhythmias in aged rats.
Materials And Methods: Myocardial IR induction was performed by left anterior descending coronary artery occlusion for 30 min, followed by re-opening for 24 hr.

Objective: This study aims to explore the role of estrogen in providing cardioprotective benefits to premenopausal women, examining how hormonal differences between sexes influence the prevalence of cardiovascular diseases (CVDs) in women.
Materials And Methods: Eighteen female Wistar rats were equally distributed into three treatment groups. Animals in Group I (sham-operated) and Group II (ovariectomized [OVX]) received oral saline solution at a dose of 2 mL/kg.
